Re: Sharp MZ-80K help needed on repair
I believe (but maybe pud can confirm again) that the original SHARP branded RAMs always test OK and that's in spite of being handled just as the other non-Sharp parts are.
Pudwink, do either of your programmers also have a chip test \ RAM test mode? Alternatively, do you have another computer, like a Spectrum, which you could test the non-Sharp RAMs in? Also did you try what I suggested, cleaning up the edges of the pins on one RAM device which always fails and then trying it again?
